Layers of ash found in the Santa Barbara Basin, in California suggest that the Yellowstone supervolcano erupted two times more than 6 million years ago. What happened as a result of these super eruptions?

A supervolcano currently lies dormant underneath the Yellowstone National Park. If it decides to wake up, we will have much less time to prepare for a disastrous volcanic eruption than researchers previously thought.

Scientists warned that if the Yellowstone supervolcano erupts, it could wipe out majority of the United States. 90,000 could be killed and rescue operations would be impossible to deploy as the affected area would be in a state of volcanic winter. Chances of a volcanic eruption are, however, very slim.

A magma chamber with enough material to fill the Grand Canyon 14 times over has been found beneath the Yellowstone supervolcano, researchers say. The finding yields insights into the 'plumbing' system feeding the giant caldera.

A Yellowstone eruption could blanket the whole of North America with ash and cause a winter during the summer months. It's unlikely to happen anytime soon, but a new computer model shows just how wide an area the eruption would impact.

The UK is facing a ticking time bomb far worse than the human-induced catastrophes of nuclear warfare and terrorism to its locals. With the revelation of a latest study, the authorities are preparing for the worst.
